Data Quality | Yahoo! Finance | Get the basics working first !
Yahoo!finance data quality is abysmal. For AORD where is Volume Data for 04Dec19 and 11Dec19 ? Where is any Data for 16Dec19 ? (16Dec19 is just missed completely !)
You just got to improve fundamental Data quality before trying to be 'clever' !
